2.2 to ecotec quick Q

I read this walkthrough: http://www.j-body.org/forums/read.php?f=2&i=239259&t=239259

For a walkthrough on the 2.2 from a 95-99 to ecotec swap, but is it any different for a 2000 2200 to ecotec? I heard from some people it would be somewhat easier. All I need to know is the differences thanks.

On top of that, would it be better to take the tranny from the ecotec and use it, or is the 2200 tranny sufficient enough? Both are auto.

99 and below tranny's were Isuzu and 00+ were Getrag.. I do belive.

If he said both are auto, the isuzu/getrag problem should be irrelevant.

Now...do the tranny's bolt on? That's a question I can't answer. I thought they were the same tranny in the auto's from 95 up, but I could be wrong. If they are the same, then there would be no gain or loss with choosing either tranny.

Blah... they are all 4t40e auto's, but they are NOT interchangeable. Starter positions are different b/w 2.2 OHV and eco.

So if I want to swap the eco I need to eco tranny? And as far as 2000 being any different than 95-99 Im taking it as a no, same rules apply all around?

Eco was from late 02-05 cavs.
